- Zephyr, Capri, and Cadet share the same basic body
and mechanical designs as their 1972 counterparts with obvious differences
on Zephyr and Capri being the elimination of foot
loop running board supports and disc brakes. MANY differences are apparent when placed
side by side to a 1972.

- Cowling redesigns for Zephyr and Capri. Back to a single
headlight. Hoods broke easily and are tough to find in good condition. - Backrest compartments eliminated on all models but Zephyr
which came with a motocycle style passenger back support (option on Capri)

- Engine clutch, bogie wheels, and other small details are actually
ski-doo designed pieces most likely used to save money in manufacturing.

- While
the tracks appear similar to the previous years, they are actually of
a different composition and so did not hold up as well. There are also
some length differences between Zephyr 340 and 440.

"F"(family) and "S"(sport)

- "F" and "S" models are first non-racing moto-skis designed for
use of slide rails only

- Tunnels are made from aluminum

- Engines are mounted forward and down into the belly-pan like
all newer sleds

-
These two models mark an end to traditional Moto-Ski engineering however are
composed of parts clearly related to previous years. Even though Bombardier purchased Moto-Ski in 1971, it
was not until 1975 that their designs began to totally replace models in
the lineup.
